Functions of proteins

Answer 1

-serve as enzymes -serve as hormones -serve as antibodies -serve as receptor molecules on the cell membrane. These are used to receive chemical messages (like hormones). dietary sources of protein are: first class, fish, eggs, milk and meat. second class are beans pulses and peas. the main functions are for growth and repair of body tissues which are used in the production of hormones and enzymes.

Answer 2

Proteins have many functions. They serve as enzymatic catalysts, are used as transport molecules (hemoglobin transports oxygen) and storage molecules (iron is stored in the liver as a complex with the protein ferritin); they are used in movement (proteins are the major component of muscles); they are needed for mechanical support (skin and bone contain collagen-a fibrous protein); they mediate cell responses (rhodopsin is a protein in the eye which is used for vision); antibody proteins are needed for immune protection; control of growth and cell differentiation uses proteins (hormones). These are just a few examples of the many, many functions of proteins.
To form cell which in turn formed many basic unit like muscle and enzyme etc.

Answer 3

Answer 4

Well from a kid that goes to Boca Ciega High School i got the answer from my teacher. Protiens build your body, and control chemical reactions.
